  Q: How to remove and install the front torsion bar spring on Toyota Land Cruiser?

  A: One must begin by taking out the front wheel and then the engine under cover before proceeding to remove the front torsion bar spring. Place matchmarks on the torsion bar spring together with the anchor arm but separate from the torque arm. Afterward remove the torsion bar spring with the anchor arm. Note the distance from the anchor arm adjusting bolt end to the frame because it will serve as an installation reference point. First free the tension in the spring through anchor arm bolt loosening then measure the anchor arm bolt "B" for future installation. Start by unfastening the anchor arm adjusting bolt and anchor arm swivel and anchor arm adjusting seat followed by the torsion bar spring removal with its anchor arm and subsequent separation of the anchor arm from the torsion bar spring. Remove the torque arm after you have taken away both nuts and the bolt and torque arm itself. Begin the installation by putting the bolt into the torque arm followed by adding the torque arm and two nuts before torquing to 225 Nm (2,300 kgf-cm, 166 ft. lbs.). The first installation step for a new torsion bar spring requires light application of MP grease to the spline before adding the new torsion bar spring with the anchor arm. Next install the anchor arm adjusting seat followed by the anchor arm swivel and then anchor arm adjusting bolt. Set the length of the anchor arm adjusting bolt to match dimension "B" which was previously measured during removal. Then tighten the bolt until dimension "A" reaches its specified measurement range. When using previously used torsion bar springs keep the matchmarks between the anchor arm and torsion bar spring in alignment before setting them with the torque arm and torsion bar spring to obtain a proper dimension "A" measurement from the earlier step. To complete the repair the engine under cover needs to be installed with the front wheel receiving a torque of 131 Nm (1,340 kgf-cm, 97 ft. lbs.) while checking vehicle height through anchor arm bolt adjustment when the suspension achieves stability.
